My new PNAS paper with Daniel Romero ! 😎 With open data everywhere, how can we creatively unlock its potential for impactful innovation? We show that unusual combinations of datasets lead to more impactful discoveries, yet even simple combos remain rare. pnas.org/doi/10.1073/pn…

Once, a big challenge of working with data was getting it. Now, researchers can select from loads of open access data sets — and when data is combined in novel ways, innovation blooms. New study by UMSI’s Yulin Yu and Daniel Romero in PNASNews: myumi.ch/kZR9z

"A Test of Time: Predicting the Sustainable Success of Online Collaboration in Wikipedia" measures the ability of collaborative efforts to maintain their quality over time + new dataset: 40K articles w/ success labels & 300 features (Israeli et al, 2024) arxiv.org/pdf/2410.19150

Honored to be selected as an EECS Rising Star by MIT EECS . The workshop was inspiring, connecting me with female role models and exposing me to exciting computer science research. It has motivated me to further tackle real-world problems by understanding human creativity.

Congratulations, Yulin! Well deserved. Yulin is on the academic job market. If you're hiring, take a look at her impressive work: yulin-yu.github.io

How do scientists choose which topic to study? Studies of this are dispersed across fields, and it's surprisingly hard to find a review. Fortunately Sidney Xiang has written a fantastic one, focusing on literature in economics and sociology (link in next comment)

How did #IGotAThingFor become a thing? Louise Zhu David Jurgens is now on BlueSky only Daniel Romero and I explored the roles of networks and identity in the adoption of hashtags in our new The Web Conference paper (Poster 01, Thu 5pm)! dl.acm.org/doi/pdf/10.114… #www2025 #thewebconf2025 1/9

Life update! I’ll join @UofAinfoSci University of Arizona as a tenure-track Assistant Professor in Fall 2026. Before that, I’ll postdoc with Brian Uzzi at Kellogg School Northwestern + visit Microsoft Research. Excited to keep exploring how data, AI, and social networks drive innovation!

Conventional wisdom says interdisciplinary research is valuable but harder to get through peer review (need to please diverse reviewers, etc). In new PNASNews paper, Sidney Xiang Daniel Romero and I partnered with IOP Publishing to test this wisdom and add nuance (1/3)
